Green Chemistry is the design of chemical products and processes that reduce or eliminate the use and/or generation of hazardous substances. The Twelve Principles of Green Chemistry 1. Prevention. It is better to prevent waste than to treat or clean up waste after it is formed. 2. Atom Economy. Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product. 3. Less Hazardous Chemical Synthesis. Whenever practicable, synthetic methodologies should be designed to use and generate substances that possess little or no toxicity to human health and the environment. 4. Designing Safer Chemicals. Chemical products should be designed to preserve efficacy of the function while reducing toxicity.
